Towards understanding astrophysical effects of nuclear symmetry energy

BA Li, PG Krastev, DH Wen, NB Zhang - The European Physical Journal A, 2019 - Springer
Determining the Equation of State (EOS) of dense neutron-rich nuclear matter is a shared
goal of both nuclear physics and astrophysics. Except possible phase transitions, the density …
